Ceramic sand-based permeable plate and preparation method thereof
The invention relates to a ceramic sand-based water permeable plate and a preparation method thereof, and belongs to the technical field of ceramic tiles. The ceramic water-permeable plate comprises a surface layer and a water-permeable base layer, and the surface layer is formed by firing fine sand with the particle size D50 of 300-420 microns as a framework material; the fine sand is mainly prepared from SiO2, Al2O3, Fe2O3, CaO, MgO, K2O and Na2O; the sphericity degree of sand grains of the fine sand is larger than or equal to 0.5. The surface layer of the ceramic sand-based water-permeable plate is prepared by sintering fine sand with small granularity and sphericity of more than or equal to 0.5 as a framework material, so that the surface layer is fine and smooth in touch feeling and less in scratching and puncturing feeling, and meanwhile, more smooth and smooth water-permeable pore passages are formed after the spherical powder is sintered, so that the water-permeable resistance can be reduced, and the service life of the ceramic sand-based water-permeable plate is prolonged. The surface layer has good water permeability; in addition, due to the fact that the water permeable pore channels formed through sintering are small, blocking of fibers and silt can be reduced, and the ceramic water permeable plate has certain anti-skid performance.
本发明涉及一种陶瓷砂基透水板及其制备方法，属于陶瓷砖技术领域。本发明的陶瓷透水板，包括面层和透水基层，面层是以粒度D50为300～420μm的细砂作为骨架材料经过烧成形成；细砂主要由SiO2、Al2O3、Fe2O3、CaO、MgO、K2O和Na2O组成；所述细砂的砂粒球形度≥0.5。该陶瓷砂基透水板的面层以小粒度的砂粒球形度≥0.5的细砂作为骨架材料进行烧结制备形成，可以使面层触感细腻，减少刮蹭刺破感，同时球状粉体烧结后形成透水孔道圆滑通畅并且数量更多，能够减小透水阻力，使得面层具有良好的透水性；此外，由于烧结形成的透水孔道较为细小，还可以减少纤维和泥沙的堵塞，并使陶瓷透水板具有一定的防滑性。
